CLASP-ATTACHING MACHINE FOR ENVELOPES AK!) THE LIKE.

Application filed August, 3, 1922. Serial. Rn. 578,378.

To all whom it may concern:

Be it known that I. HARRY Lavish, a citizen of the l'nited States, residing at Brook lyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Clasp-Attaching Machincs for Envelopes and the like, of which the following is a specification.

This invention relates to clasp attaching machines for envelopes and the like, and more particularly to mechanism for attaching to envelopes pronged eyelet clas )8 or clips which in use cooperate with rein orced perforations on the tin s of the envelopes, the latter being formet by suitable mecha nism preferably forming a part of the pres ent machine and operativc simultaneously with the clasp attaching mechanism, an object of the present invention being to provide an ilnprored machine wherein the clip or clasp applying mechanism and the feed channel for guiding the pronged clilps thereto are so constructed as to be simu tune-ousl r adjustable, or shiftahlc together into vu- Iioits positions.

A further ohject of this invention is to provide an improved clasp attaching machine having an improved feeding mechanism for permitting the proper tccd ot' the clasps or clip's. such mechanism lieiug posh.

tivcl v operated as h cumming means thinnliy eliminating the necessity for using springs which are short lived and which often break. thus stopping the operation of the machine until they are repla ed.

A further object of this invention is to provide an improved means for feeding the clips to the clip applying mechanism. which means in the present lint inure is substantially a two-step feed. and/is adapted to permit faster operation oil the clip applying mechanism due to the utilization of the time required for the withdrawal and forward movement of the punches in feeding the clasps or clips into the path thereof.

A further object of this in ention is to provide a clasp attaching machine 'hafih means shiftablc into and out of the path of operation of the eyelet riveting means for successively feeding the clasps thereto. In the present instance such means is operated in conjunction with the escapenient means, the latter feeding the Clasps successively to this shiftable means, which is operated at predetermined times to shift the Cl p n one direction into position to be enu geo b the riveting means, and is shifted in the posite direction at predtt *rrnined times out of the path of the rivetir .ueuns.

A further object of this nvention is to provide an escapement mechanism comprismg rotatable and preferably intermittently rotatable means and clasp positioning means for receiving the 'clasps from the rotatable means; both of said means being positively controlled by a common means and in the present instance intercontrolled.

A further object of this invention is to provide in u clasp attaching machine means for adjusting the feed channel and riveting punch without withdrawing the latter and. also to provide ncans for permitting the punch to he adj sted and removed without removing it endwise or axially from its support.

Other objects of this invention will appear in the following description thereof. reference heing had to the accxnnpanying drawings forming at part of this specification wherein like refcrcn e characters indicate corresponding parts in the several views and wherein Fig. i a side elevation of a machine ernluu'lying my invention; Fig. 2 is a plan VlEW illustrating certain operating parts, others being removed and broken away for clcaruess; Fig. 3 is a detail elevation illustrating the feed channel and particularly the manner of adjustment thereof; the support for the riveting die being shown at the reverse side of the channel from that in Fig. 1: Fig. l. a front clto'ntion of the feed channel paitlv broken away and other operating parts. the riveting die support and feed slide being shown at the reverse side of the feed channel from that in Fig. 1; F ig. 5 illustrates a pronged eyelet clasp or clip; Fig. 6 illustrates the perforated patch whit-his attached to the envelope shown in Fig. 16 Fig. 7 is a detail view illustrating articularly the clasp feeding mechanism; ig. 8 is a detail front elevation thereof; Fig. 9 is a detail view illustrating the sup port for the riveting punch: andFig. i0 is a view of an envelope with u pronged eyelet clasp attached thereto.

in the drawings wherein l have illustrated a preferred embodiment of my invention, it will be seen that the present machine comprises av suitable bed or table 2 provided with end bearings 3 for supporting the cam shaft 4 having at one end the usual hand Wheel and at the opposite end a driving wheel 6. Carried by the cum shaft are a pair of cams 7 and 8 adapted to :o-

,oerate with a pair of cum levers 9 a ll Ill ihllcrumecl at 11 and '12 upon the bed. I'hese overs are connected to the patch (lie mechanism 13 and l-l for the purpose of operating the same. Curried in suitable hearings 15 and 16 at the opposite side of the bed of the machine is a patch (lie tube 17 which is operated by means of a cannlever 18 secured thereto and fulcrnmed on the bed at 19. This lever is provided with n roll 20 running in the ram 21 carrierhhr the cam shaft l. Secured to the tube 17 is a laterally extending supporting sleeve :22 for the punch of the clip or clasp attaching mechanism. This sleeve 2:2. it will be noted. reierring particularly to Fig. 9. is bored at 24 to receive the tube- 17 and is also protitled with an open slot 25 for acljustahly and remoi'ablv receiving and supporting the punch The punch is held in position in the slot by means of adjusting collars or nuts 26 threaded to the punch and located at either side of the sleeve 22. The punch 23 at its o erating end, is bored to receive the tube 2: and is couuterhored to receive a spring 28, which impinges against the head of the centralizing pin '29. A further detailed description of theoperating mechanism of the machine is not deemed necessary herein as this construction is well known in the art.

Extending from the bed of the machine is a suitable standard or support ill) constructed for the purpose of supporting the feed channel 31 for lateral adjustment. The feed channel may be of any suitable construction and the clips or clasps 32 are fed thereto hy means of a hopper 33. A detailed rlescription of the hopper mechanism and the feed channel per se not deemed necessary herein as thesame may he of any desired construction as is well known in the art.

The frame extension or support is provided with a suitehle guideway cooperating with a guide portion 3-l extending: from the feed channel. the latter being adjusted laterally in the guideway of the support 30 by means of set screw 35 extending into a hole. 36 in the guide 34 of the feed channel and adapted to be loosened so as to permit lat eral adjustment in a. slot 37 of the support 30. In order to avoid the disadvantages of separate adjustment of the feed channel and clasp attaching mechanism, the present organization is such as to permit simultaneous adjustment of the feed channel and clasp attaching mechanism. Bolted to the side of the feed channel as at 38 is :1 depending bracket or supporting arm 39. the lower end thereof having a part 40 extending laterally across the path of operation of the ".usp attaching: mechanism. The (lie mean her or anvil ll coni nisiug (OUlJLlllllllg part of the clasp or clip applying means is carried by the extension ll] of the bracket 39. Thus it will be seen that upon adjust ment of the feed channel the die member -31 w ll also be simultaneously adjusted. The forward operating, eml of the punch it will he understood operates in a hole extending through .lie lower end of the feed hannel, the punch having a bearing in a boss 42 carried at the rear of the feed channel. Not only is the die member 41 shifted into adj usted positions with the feed channel. but the construction is such that the punch 23 is also sin'uiltaneously adjusted therewith and without necessitating either the re moral of the punch from the fecal channel or the removal of the punch from the support 22. This simultaneous adjustment of the channel 31', riveting punch 23. and die member 41 is readily accomplished by loosening the collars or nuts 26 carried in the punch, and by loosening the adjusting screw 35. and then shifting all of the parts together into their roper positions. the leterol adjustment o the punch being permit ted by virtue of the slot 25 in the support Furthermore since the slot 2.") is open. the punch can be readily removed merely by unscrewing the nut 26. withdrawing the punch 23 from the feed channel and then shifting it transversely out of the slot For the purpose of properly feeding the. clasps into pro )er attaching position and at the same time or the purpose of preventing the loss of any time due to the reciprocation of the riveting punch 23, I have provided improved cfidapement mechanism which preferably comprises improved means for successively releasing the clusps and also means for receiving the clasps therefrom and shiftahle into and out of the path of operation of the punch for positioning the clqs rs relatively thereto. The clips or clasps are fed from the ho per 33 into the channel or trough 43 of the 88d channel proper. and in the present instance the clips are engaged and released successively by means of a rotatable drum or other member 44 mounted on a shaft 45 carried at the upper end of a standard or other extended bearing member 46. In the present instance the wheel or drum 44 i provided with spaced projections or teeth 47. which upon rotation of the wheel are carried into the path of the clips 32, one tooth or projection moving into position hcneuth the central projecting part of a. clip and supporting the column of clips while the projection or tooth nest below releases a clip. The clips are guided endwise in the channel and fed by gravity in overlapping relation as shownin Fig. 8 and it will he noted that the teeth or projections 47" are spaced apart a distance less than the into position beneath the clip above.

length of a clip so that when the lowermost 'clip is released byga projection the next sucing projection will simultaneously moye n the present instance the rotatable member 44 is rotated intermittently or in a step by step manner, which may be accomplished by means of a ratchet 47 secured to the member 44 and a pawl 48 pivoted to an oscillating lever 49 journalled on the shaft 45. At its outer end the arm or lever 49 is provided with a de nding forked member 50 having hifurcate ends freely embracing the cam shaft 4 and provided with a cam roll 51 enaging a cam 52 mounted on the cam shaft. t will be'understood that in operation the cam 52 will cause the member 50 to he reciprocated in a vertical plane thereby operating the ratchet and pawl mechanism and rotating the drum 44 intermittently.

- The clips after being released from the escapement wheel 44 are positively guided into attaching position by means of a shiftahle mechanism which in the present in stance is carried b the feed channel. This mechanism as herein shown may comprise a slide 53 having guide slots 54 for receiving guide screws 55 secured to the feed channel. The slide 53 it will be seen may have a shiftahle movement measured by the length of the slots 54 and the range of movement may be adjusted by adjustingthe vertical position of the screws 55. At its lower end the slide :13 has a right an led extension terminating. at the channe 43 and slidahlc over the front face of the feed 'channcl proper. A guide stop 57 is pivoted at to the extensionotl and is preferably hook shaped to form a seat for the clips. This stop 57 is controlled by means of a spring 5!). A coiled spring 60 may be secured to the upper end of the slide and also connected to the feed channel for retracting the slide. and the latter is provided with an extension 61 extending into the path of the teeth 47. In the operation of this combined feeding and escapemcnt mechanism, it will he seen that as the whccl 44 rotates and the lug or projection 47 moves downwardly (see Fig. to release a clip. the same projcction 4T w'll also engage the projection 61. thus shifting the slidc dmvnwm'dly. lmnicd'c ately upon the seating oi' the clip 32 upon the stop 57. the latter will he carried by thc slide into the path of operation oflhe punch 23 and. lllPl'tlltlUW so as to guide lhc clip into alinemcnl with the punch as shown in dotted lines in Fig. 8. The punch is then shifted forwardly hy the camming mechanism, and as soon as the centralizing pin 29 engages and is centralized in the eyelet 32 of the clip or clasp. the lug or tooth 47 in its movement is disengaged from the projection 61. the slide being immediately retracted by virtue of the spring 60. The hooked end of the guide stop 57 is also retracted since the pivotal support thereof permits the same to be swung out of engagement with the clasp against the spring 59. During the completion of the rivcting operation and the retraction of the punch. a new clip may be released by the cscapemcnl wheel and seated on the guide si op 57.

Referring to Fig. 1 it will hc sccn that the slide 53 may he retracted hy mcnns of n cam 62 secured to the sleeve 22 and having the forward end thereof engaging a suitahlc roll or pin 63 on the slidc. This com 6:! will he so constructed as to causc thc some to engage the pin 63 and retract the slide during the forward operative niovcmcnt of the punch. It will he understood of coursc that thc pronged eyelet clips or clasps 25;! may he a tached hy the present nlccluinism to an envelope 65, other mechanism in the machine. not forming a part of this invention. being preferably cmploycd to form the reinforced perforation 68 in the flap of the envelope.

It will he understood that thc mechanism is so timed that the punch will engage the prongcd eyclcl clip at the instant the food slide 53 reaches its lowcr position. and at this instant the tooth or log of the cscapcment wheel in its rotation is disengngcd from the slide. lhcrchy permitting the spring 60 or can] 62 or hoth to positively retract the slide and pcrmit unothcr clip to he released and seated on the guide stop 5?. operation of this machine by virtue of this combined or two-step feed or control of the clips. since it is not necessary for the punch to be withdrawn or released hcforc a clip can he released by the cscapcmcnt wheel.
